Can Shanghai be a roommate after receiving SMS on epidemic prevention and control?

You can't. According to relevant information in official website, the phrase "epidemic prevention and control" will query your location not only according to the location of your household registration, but also according to the location of your mobile phone, so you'd better stay at home and wait for the notice that the people who live together will stop working. For specific information, please pay attention to official website for first-hand authoritative information.
